honya96 said:I have 20s14p pack of used laptop 18650. Calculate with using max 6A per cell for really short bursts or 4A for a bit longer. Best to install 1$ lcd with temp sensor to keep battery under 60°C if you want to push it.
72v 40A 12fet controller can't handle hallomotor 48v 1000w motor (no load rpm at 20s is around 1150, so its asking too much phase current.) So look it up and get lower rpm motor than this one or/+ 72v 45A 18fet on Aliexpress for around 82$ it can handle 45A for much longer than 12fet its 40A rating.
25$ taxfree EU limit is not including shipping so you can ask seller to declare 22$ product + 38$ shipping and send you invoice with these prices so it can pass tax free even if they stop it.
I will make it 20s20p with tesla fuses to be super safe. Good idea to put 1$ lcd sensor now its in my todo list.
Can you give me a link from aliexpress for kt controllers because i want to use opensource firmware.
Our customs is really hard to trick. But if they stop my package i can pay for tax its not big deal.
Thank you
